Research
My research interests lie in the field of systems and control. I aim to develop a systems and control theory that is grounded on measured data. I work towards mapping raw data into models and control policies with rigorous guarantees on accuracy, stability and performance, while answering key questions such as: how much data is needed? how to handle noise? and how to perform control-relevant experiments?
Some of the specific topics of interest are:
Direct data-driven control
System identifiability
Kernel-based identification of (physical) dynamical systems
Experiment design
Applications to networked systems and neuroscience
We have recently approached the question of how much data is required for control via the concept of informativity, which is explored for several control problems in:
To address robustness of controllers with respect to noise and bounded nonlinearities, I have worked on generalizations of the S-lemma and Finsler's lemma:
Quadratic matrix inequalities with applications to data-based control
From noisy data to feedback controllers: non-conservative design via a matrix S-lemma
A matrix Finsler's lemma with applications to data-driven control
Kernel-based modeling for systems with (incremental) dissipativity properties is treated in the papers:
Some other recent work involves the problem of experiment design:
A persistency of excitation condition for continuous-time systems
Beyond persistent excitation: online experiment design for data-driven modeling and control
Willems’ fundamental lemma for state-space systems and its extension to multiple datasets
